🔌 Hardware & Wiring

Note: This firmware uses INPUT_PULLUP. Buttons must connect to GND when pressed. No external resistors required. ⚠️ Update the #define pins in each .ino file to match your actual build.

Module	Arduino Pin	Function
Nokia 5110 RST	D11	Reset via 10kΩ
Nokia 5110 CE	D10	Chip Enable via 1kΩ
Nokia 5110 DC	D9	Data/Command via 10kΩ
Nokia 5110 DIN	D8	Serial Data
Nokia 5110 CLK	D7	Clock
Nokia 5110 VCC	3.3V/5V	Power
Buzzer (+)	D6	via 1kΩ
Button UP	D2	GND
Button DOWN	D3	GND
Button LEFT	D4	+ 10kΩ to GND
Button RIGHT	D5	+ 10kΩ to GND

💡 The Nokia 5110 uses 3.3V logic. Most Nano clones include onboard level shifters. If yours doesn't, add 3.3V/5V level shifters for D11–D7 or use resistors.

🔧 Perfboard Wiring Tips

• Connect all button GND pins together, then to Arduino GND.
• The Nokia 5110 requires 3.3V logic. Most Nano clones handle 5V→3.3V shifting internally. If your LCD flickers or stays white, add a 10kΩ potentiometer to the V0 pin for contrast tuning.
• Use INPUT_PULLUP mode in setup() to avoid floating pins and external 10kΩ resistors.

🚀 Getting Started

1. Install Arduino IDE (v2.x recommended)
2. Install Libraries: Sketch → Include Library → Manage Libraries → Install:
   • Adafruit GFX Library
   • Adafruit PCD8544 Nokia 5110 LCD Library
3. Upload Firmware:
   • Open your preferred .ino from firmware/
   • Board: Arduino Nano
   • Processor: ATmega328P (or Old Bootloader if upload fails)
   • Click Upload
